【 摘 要 】

In order to investigate the elements doping effects on expansion ratio, a series of Zr1-xCexSiO4(0.01 ≤ x ≤ 0.05) ceramics were synthesized by high temperature solid state reaction, and the expansion ratio was systematically studied. The results show that the element doping has significant influence on the expansion ratio. The radial, axial and volume expansion ratio of Ce-doped zircon ceramics decrease in the Zr1-xCexSiO4compounds from x = 0.01 to x = 0.05. Furthermore, it also found the changes of Zr1-xCexSiO4(0.01 ≤ x ≤ 0.05) before and after sintering size in detail. At the same time, these results indicated that Ce-doped zircon ceramics good performance in expansion ration.
